' .T-YPEWRITING momma Filed Aug. 15, 1927 Mum/w? Patented June 10, 1930 UNITED STATES PATENT OFFICE CARL E. NORIN, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO UNDERWOOD ELLIOTT FISHER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE TYPEWRITING MACHINE Application filed August 15, 1927. Serial No. 213,131.

This invention relates to means for holding labels, cards, or the like on the typewriter-platen. Such devices are usually made of resilient sheet-metal (substantially in the form of open sleeves) to be clasped around the platen to rotate therewith. The holder is usually self-sustaining or provided with means for gripping the platen, and it also holdsindependently the card or label upon the platen.

According to the present invention, a main clasp extends more than half way around theplaten, to enable the device to securely retain itself upon the platen, and a more yielding paper-clip or finger is normally tensioned upon the platen and has the form of a frame surrounding one end of the main clasp, both the frame and the main clasp preferably being inexpensively and compactly struck out of a single sheet of resilient material forming a light structure. The card or label is inserted by its lower margin between the forward gripping edge of said resilient frame and the platen, said frame, as a whole, becoming separated slightly from the platen, without weakening the firm grip of the main clasp around the platen.

, Preferably two platen-clasping tongues, side by side, are stamped out of an open sheet-metal sleeve adjacent a longitudinal edge thereof, in such a Way that an E-shaped frame is created to serve as a paper-clip,

said frame surrounding said tongues. The frame is formed with the. three parallel cross-bars extending out of the body of said sleeve and alternating with said tongues; and a longitudinal bar completes the E-shape, joining the three parallel bars in front of the tips of said tongues. Said longitudinal bar forms the gripping edge to hold the paper. This device affords great flexibility and adaptability to the platen.

Another feature consists in the provision of outwardly-raised portions as ribs or wards upon the main clasp, so as to keep:

certain typewriter parts adjacent the platen away from the yielding frame, to-secure unrestrained flexibility thereof wlthin certain limits, so that a card or label may be readily inserted and held in place without danger of the pressure of the frame being altered.

The device is reliable in operation and easily attachable and detachable.

The invention is shown to be applied to an Underwood portable typewriter.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure l is a partially sectioned perspective view of the detached novel labelholding device.

Figure 2 is an end view of the detached label-holding device.

Figure 3 is a cross-sectional elevation, showing the novel label-holder mounted in place upon the platen when a card or label is being inserted, and showing ribs provided upon the holder being effective to keep the usual paper feed-rolls and the front scale out of contact with the workgripping yielding frame.

Figure 4 is a perspective view, showing the novel device clasped around the platen with a card inserted in writing position. said card abutting the tips of platen-gripping tongues as a bottom gage. The usual front scale is partly broken away to more plainly disclose the ribs in their action of warding the scale away from the flexible frame of the label-holder.

Figure 5 is a cross-sectional elevation to illustrate a novel manner of detaching the device from the platen.

Referring in particular to Figure 1, the novel card-holder 10 substantially has the contour of a plain open sleeve and is made of resilent sheet-nietal to be clasped around a platen 11 (see Figure of a typewriter. The open sleeve has longitudinal edges 12 and 13 and sloped edges 14 at the sides, thereby forming two opposed tapers having their base at a longitudinal central portion 15 of said sleeve and their heads at said edges 12 and 13 thereof. The holder is, however, adapted for the double task of rather firmly gripping the platen, and, on the other hand, of more resilently holding cards or labels to be Written upon. To this end,

shaped slots 16 so as to create two relatively wide tongues 17, which, together with the body-part 18 of the sleeve, are to securely grip the platen wherever said sleeve is attached thereto, and also to create an E-shaped frame 19 around-the two tongues which is to serve as a paper-clip fo'r "attaching cards or labels to the platen, said Eshape includling threearelatively narrow parallel crossbarsQOeXtending from the body-part 18 and alternating with the tongues 17, and a longitudinal bar 21 in front of the tips of the tongues and joining the ends of said crossbars in completion of the E-shape. yielding paper-clip in the form described above affords a desired large paper-gripping edge in conjunction with comparatively large platen-gripping front edges. It is I flexible and well adaptable to the platen,'yet

effectively resisting distortion. The whole arrangement is, over prior constructions of similar character, compact andhandy.

Figure 2 more clearly illustrates the differentiated springing and gripping qualities of the holding device; The device substantially conforming to the curvature of the platen is shown in unstressed condition to have the tongues 17 normally deviate from the circular shape of the platen just far enough inwardly to enable the clasp, when being distended and sprung "around the platen, to securely hold the device in place thereon, while the yielding paper-gripping frame 19 only slightly engages the circum ference of the platen and will not exert considerable pressure upon the platen, although sufficient to hold the card or label thereon platen, is shown in Figure 3 engaging the lower part of the platen, the yielding. frame then being-in front of the platen to show a .card 22 when being inserted and gripped by its lower margin. Inserting a small workpiece by its lower margin is convenient and only requires a fraction of a full turn of the platen backwardly' for positioning. The gripping edge 12 of the .yielding frame is beveled, as shown, to facilitate insertion of the card. I I

It moreover appears from Figure 2 that 1 ribs 23, according to the invention, provided upon the tongues 17 and reinforcing the The r a feed-roll-release mechanism at 81 is indi-' cated in dot and dash.

As the ribs 23 clear the way, as shown, they afford unrestricted flexibility of the yielding frame between the warded off front scale or feed-rolls and the platen, so that the card or label 22 can be readily introdu'ced between the gripping edge 12'Jof the yielding frame and the platen 11, said card being held by the frame while the platen is rotated backwardly tobring the label down to the printing line, as indicated in Figure 4. When the label is inserted its bottom edge rests against the tips of the clasp-tongues 17 (see Figure 4), which therefore are a bottomgage for the label, wherebythe forward ends 31 of the ribs 23, forming part of the abutment, serve to prevent the card frombeing thrust over the tongues, that is, beyond" the gage line. The label isheld in proper position throughout the forward and. backward rotation of the platen, and it should be understood that the top'edge of,

the label may be held against the platen by usual paper-fingers, rollers or the like (not shown in the drawings).

Due to its compactness the device is. easy to handle' Having straightlongitudinal edges and rounded corners, the clasp readily slips over the platen without danger of scratching or injuring the platen-surface, and grips the platen for a firm seat; The tapering ofthe holder from its central bodyportion towards its extremities 12 'and '13, as mentioned above, increases-the flexibility ofthe holder towards said extremities-and thereby facilitates its application to the platen, said central body-portion being .wide enough to properly seat the device as "a whole upon the platen. I I I Moreover, the device, as herein described, will largely facilitate the detachment thereof, which generally is troublesome due to the flatness and'close fit of such appliances and due to liability of scratching the platensurface. I

According to a novel method of detaching the label-holder, the platen, according to Figure 5, is rotated backwardly, as indicated by arrow 32, until the longitudinal edge 13 of the clasp engages lengthwise the edge of the movable fr'ont scale 25, which, by the operators finger, is pressed against the platen. A slight additional turn given to the platen 11 will cause the holder to smoothly slip off the platen Without excessive manual force being applied thereby injuring the platen-surface, and With the yielding frame 19 not offering obstructive resistance.

Variations may be resorted to Within the scope of the invention, and portions of the improvements may be used Without others.

Having thus described my invention, I claim:

A Work sheet holder comprising a body portion and a resilient E shaped frame extending therefrom, a plurality of less resilient tongues extending between the branches of the E shaped frame and adapted to clasp a typewriter platen, the outer ends of said tongues forming abutments for a Work sheet While the longitudinal outer edge of the E shaped frame extends in front of and around said tongues and is adapted to clasp said Work sheet.
